Tent support

Abstract

A tent support includes a plurality upright rods, a top module provided at a center of a top of the tent support, a plurality of side rod assemblies each connected to every adjacent two of the upright rods, and a plurality of top rod assemblies connected to the side rod assemblies and the top module. At least one positioning hole is provided at a junction of two adjacent side walls of each upright rod. A sliding seat provided on each upright rod includes a positioning member which is selectively engaged in the positioning hole, a spring, a positioning pin and an outward protruding button therein. The tent support, as a whole, is simple in structure, easy to assemble, and stable in positioning.

What is claimed is: 
     
       1. A tent support, comprising a plurality upright rods, a top module provided at a center of a top of the tent support, a plurality of side rod assemblies each connected to every adjacent two of the upright rods, and a plurality of top rod assemblies connected to the side rod assemblies and the top module; a fixing seat being mounted at a top of each upright rod, a sliding seat being mounted on each upright rod to slide along each upright rod so as to move the side rod assemblies and the top rod assemblies, the side rod assemblies being connected to the fixing seats of the upright rods, at least one positioning hole being provided at a junction of two adjacent side walls of each upright rod, the sliding seat including a positioning member which is selectively engaged in the positioning hole, a spring, a positioning pin and an outward protruding button therein, the positioning pin running inward through the sliding seat and through the positioning member, an engaging groove being provided on an end surface of the button facing the positioning member, one end of the positioning member being engaged in the engaging groove, one end of the spring being abutted against the button, another end of the spring being abutted against an inner wall of the sliding seat. 
     
     
       2. The tent support as claimed in  claim 1 , wherein the positioning member is an elongated bar. 
     
     
       3. The tent support as claimed in  claim 1 , wherein the upright rods are rectangular rods, and the positioning member is  -shaped. 
     
     
       4. The tent support as claimed in  claim 1 , wherein a further positioning pin is provided between the button and the positioning member, and the end of the positioning member has a slot for limiting movement of the further positioning pin. 
     
     
       5. The tent support as claimed in  claim 1 , wherein the top module includes an upper runner and a lower runner, each side rod assembly includes two link rod units hinged at respective ends to each other, each top rod assembly includes a link rod unit, each link rod unit of each side rod assembly includes two link rods that are hinged to each other and expanded into an “X” shape, first ends of the two link rods of the two link rod units of each side rod assembly are hinged to each other to form an upper hinge point and a lower hinge point, second ends of the two link rods of the two link rod units of each side rod assembly are hinged to the fixing seats and the sliding seats of the adjacent two of the upright rods respectively, the link rod unit of each top rod assembly includes a long rod and a short rod that are hinged to each other and expanded into an “X” shape, one end of the long rod of each top rod assembly is hinged to the lower hinge point of a corresponding one of the side rod assemblies, another end of the long rod is hinged to the upper runner of the top module, one end of the short rod of each top rod assembly is hinged to the upper hinge point of the corresponding side rod assembly, and another end of the short rod is hinged to the lower runner of the top module. 
     
     
       6. The tent support as claimed in  claim 5 , wherein the top module further includes a central rod, and the upper runner and the lower runner are arranged on the central rod. 
     
     
       7. The tent support as claimed in  claim 6 , wherein the upper runner is slidably arranged on the central rod, and the lower runner is fixed at a bottom end of the central rod. 
     
     
       8. The tent support as claimed in  claim 1 , wherein a top of the top module is a circular plate, a runner is provided under the circular plate, each side rod assembly includes two link rod units hinged at respective ends to each other, each top rod assembly includes a link rod unit, each link rod unit of each side rod assembly includes two link rods that are hinged to each other and expanded into an “X” shape, opposing ends of the two link rods of the two link rod units of each side rod assembly are hinged to the fixing seats and the sliding seats of the adjacent two of the upright rods respectively, the link rod unit of each top rod assembly includes a long rod and a short rod that are hinged to each other and expanded into a linear shape, and a support rod having two ends hinged to the sliding seat and the long rod respectively, one end of the long rod is hinged to one end of the short rod, another end of the long rod is hinged to the fixing seat, and another end of the short rod is hinged to the runner of the top module. 
     
     
       9. The tent support as claimed in  claim 1 , wherein a bottom of each upright rod is provided with a retaining part. 
     
     
       10. The tent support as claimed in  claim 1 , wherein each upright rod is formed by connecting and fixing a plurality of small rods through a fixing member.
